Snmp Implementation - Siemens 9810 Series User Manual

SNMP implementation

64
MIB files
Your meter is compliant with MIB-II as defined by the standard MIB file RFC 1213.
SNMP requires that you load your meter's ION MIB file (available for download
from www.usa.siemens.com/pds) into the NMS.
You must install RFC 1213, which is required to read basic network information for
the meter (for example, TCP/IP traffic or number of packets received), if it is not
included with your SNMP manager software.
Community strings
A community string is a text string which acts to help authenticate requests from
the NMS to your meter.
There are two community strings on your meter:
• Read Only Community: this community string is used by SNMP get (read-
only) requests. The read only community string's initial factory-set value is
public.
• Read Write Community: this community string is used by SNMP set (read/
write) requests. The read write community string's initial factory-set value is
private.
NOTE: You can also use the read write community string for SNMP get (read-
only) requests.
If your meter receives an incorrect community string, it generates an
AuthenticationFailure trap.
System strings
A system string is a text string which can be configured to provide information
about your meter.
There are three system strings on your meter:
• System contact: enter the name of the SNMP system administrator.
• System name: enter a descriptive name for your meter.
• System location: enter a description of your meter's location.
SNMP trapping implementation
Generic SNMP traps supported by your meter are:
• Coldstart: the meter (SNMP agent) is starting.
• Linkup: the SNMP agent is enabled.
• AuthenticationFailure: the meter (SNMP agent) has received an incorrect
community value.
Enterprise-specific SNMP traps supported by your meter are:
• Low: trap of events with a low event priority.
• Medium: trap of events with a medium event priority.
• High: trap of events with a high event priority.

NOTE: The number of events or maximum time delay settings only apply to
enterprise SNMP traps.
